This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ25X25-10-S, with the same bore, stroke, output force, port and mounting, so it fits the same application. The MBLJ replacement upgrades to a riveted rolling-packed body and CMSG / DMSG / EMSG sensors (the MAL used CS1-M / DS1-M).

About the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X25-10-S
The AirTAC MALJ25X25-10-S is a discontinued double-acting, double-rod mini cylinder with a 25 mm bore and a 10 mm rear travel adjuster. This yields a usable stroke window of 15-25 mm. The direct replacement is the MBLJ25X25-10-S, matching the bore, stroke, G1/8 port, and 10 mm adjust code.
The rear adjuster sets the end position but is a travel stop, not a lock; it will not hold a load without live air. This SKU includes a magnet (-S) for CS1-M / DS1-M switches, whereas the MBLJ replacement uses CMSG / DMSG / EMSG sensors. The original MALJ features threaded covers and a fixed rubber bumper, while the MBLJ upgrades to a riveted rolling-packed body. Mounting is FA or LB only; there is no back-cover or SDB option.

The rear adjuster is a travel stop, not a lock — it sets the end position but does not hold the load without live air. No back-cover code and no SDB on adjustable-stroke. The MBLJ25X25-10-S carries the same ratings.
Theoretical Output Force (Ø25mm)
| Pressure | Push force | Pull force |

| 0.7 MPa | 289 N | — |
| Max (@1.0 MPa) | 42 kgf | |
MALJ is double-rod: the rear rod that carries the stroke adjuster passes through the rear cover, so both piston faces lose rod area. Push is shown at the annular-area value (conservative), lower than a single-rod MAL push of the same bore. The MBLJ25X25-10-S matches these values.

Replacing the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X25-10-S with MBLJ25X25-10-S
To replace the MALJ25X25-10-S with the MBLJ25X25-10-S, verify the 25 mm bore, 25 mm stroke, 10 mm adjust code, G1/8 port, and FA or LB mounting (no back-cover or SDB). Remember the rear adjuster is a stop, not a lock. The -S magnet switches from CS1-M / DS1-M to CMSG / DMSG / EMSG.
Upgrade checklist
- ✓ Order the MBLJ25X25-10-S (same bore/stroke/adjust)
- ✓ Same 15–25 mm adjustable window
- ✓ Adjuster is a stop, not a lock
- ✓ No back cover / SDB — plan an FA/LB mount
- ✓ Sensor: swap CS1-M/DS1-M → CMSG/DMSG/EMSG
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.1 – 1.0 MPa operating pressure.
- check The rear adjuster sets the end position — it is not a load lock.
- check No back-cover / SDB on adjustable-stroke — use FA / LB.
- check Front/rear covers are threaded — not for field disassembly.
- check For new builds, specify the MBLJ25X25-10-S instead of this discontinued model.
